Efficient and Convenient Procedure for Preparation of N‐Sulfonylimines Catalyzed by Montmorillonite K‐10

Abstract

A general and practical chemical route to the synthesis of N‐sulfonylimines using montmorillonite K‐10 as the catalyst is described. This method provides several advantages such as operational simplicity, short reaction time, using of inexpensive materials, noncorrosivity, lack of pollution, and high yields.
